Affordable heaters for big rooms need to work harder than small-room models: wider oscillation, infrared heat, or a convection panel that spreads warmth evenly. The four picks below keep the price reasonable while covering roughly 250–300 sq ft each, according to manufacturer ratings.
We compared them on coverage, controls, noise and safety using specifications and owner feedback. For more options see our best value space heater for large room guide; our Editorial Policy explains our process.
